When you love someone you don't see anything wrong with them. Even if you see some fault in them, you justify the fault and say, "Well, everyone does it! It is normal".
Then you think you have not done enough for them. The more you do, the more you want to do for them. And they are always on your mind. You want to see them happy, you want them to have the best, and you get hurt even over small things. Ordinary things become extraordinary when you are in love.
